Better Speech-in-Noise Testing: Demonstration with Dual Variable Speed Compression

How do we assess the speech-in-noise performance of hearing aids in real-life settings to obtain clinically meaningful results? This article looks at several problems related to this issue, including what might constitute “real-life” SNRs and test environments, the variability of patient test scores at different SNRs, and the nonlinearity of modern hearing aids, using the new Widex dual-variable speed compression system as an example.
